Title: Improvements in mechanisms for adjusting the start of injection in fuel injection pumps
IPC: F02M41/14
Filed: 1962-03-30
Abstract: 993,888. Fuel-injection pumps. ROBERT BASCH G.m.b.H. March 30, 1962 [April 1, 1961], No. 12317/62. Heading F1A. A mechanism for adjusting the timing of injection in response to variation in engine speed in a fuel injection pump comprising a rotor 4 housing pistons 7 engaging an angularly adjustable cam track 2, comprises two adjusting pistons 11, 12, one slidable within the other, said adjusting pistons being actuated by the delivery pressure of an engine-driven feed pump against the action of two springs 15, 19. Spring 15 acts to force pistons 11 and 12 apart and spring 19 urges piston 12 against the feed pressure. The feed pump pressure acts on pistons 11 and 12 via passages 24, 26, 27, 28 and 29 and working chambers 25 and 30. Pistons 11 and 12 assume the positions shown when at rest and during starting of the engine, starting speed being lower than idling speed. During a first speed range after the engine has started, the injection timing is retarded, piston 11 being moved against spring 15 until it abuts the end 16 of piston 12. With further increase in engine speed, piston 12 is moved against spring 19 thereby advancing the injection timing.

Abstract: 1,146,151. Extruding. NATIONAL RESEARCH DEVELOPMENT CORP. 23 March, 1966 [23 March, 1965], No. 12326/65. Heading B3P. A continuous solid billet 23 is hydrostatically extruded from a pressure chamber 2 through a die 25, and further lengths of billet are admitted to the pressure chamber through an opening 14 which is sealed during extrusion. The billet is fed into the chamber by feed rolls 18 and is then gripped by a split or deformable collet 13 actuated by an hydraulic ram. The leading end of the billet is shaped at (21), (22), Fig. 1 (not shown), to fit into the die orifice. A seal (16), Fig. 1 (not shown), prevents escape of pressure liquid from the chamber. The liquid, which may be a mixture of methyl alcohol and castor oil, is pressurized by a plunger 24 carrying the die 25 and actuated by an hydraulic ram 28. This causes extrusion through the die and tube 30 to traction rolls 36. Seals 26 of beryllium copper with rubber 0-rings are provided for the plunger 24 and the end cap 3. The pressurized liquid may also act upon the outside of the die to support it during extrusion. Make-up liquid is supplied through duct 38 and valve 37. The extruded product may pass directly into a second or through a series of similar extrusion devices. Several billets may be extruded simultaneously through separate dies in the chamber which may be rotated during charging. Extrusion may be performed at elevated temperatures. In an alternative embodiment both the inlet and outlet passages are formed in oppositely moving plungers. Deforming members such as rolls or forging platens may act upon the billet within the pressure chamber. A futher billet may be included on the end of the existing billet to provide continuous extrusion. The apparatus may be controlled automatically by sensing means for the length of billet in the chamber or for the length of extruded product. In another embodiment, Fig. 1 (not shown), the die (8) is stationary and high pressure liquid is admitted to the chamber through duct (5).

Abstract: 1,110,367. Automatic exchange systems. INTERNATIONAL BUSINESS MACHINES CORPORATION. 23 March, 1966 [2 April, 1965], No. 12713/66. Heading H4K. A switching network comprises a number of closed meshes defined by conductors arranged in a co-ordinate manner, the intersecting points or nodes being provided with switches for connecting together any pair of conductors. In a 2 co-ordinate network, Fig. 1, subscribers' lines are connected to the nodes N over switches A, and each node may be connected to any one of 4 adjacent nodes over switches X, Y, the object being to interconnect pairs of subscribers over the shortest available path with a low blocking factor in relation to the switching equipment employed. The blocking factor may be further reduced if provision is made for rearranging existing connections. Thus, for example, with the 4 existing connections shown in Fig. 3a, if a connection is required between B33 and B43 it can be obtained by changing the B32, B44 connection to that shown dotted in Fig. 3d. The average path length of a connection may be reduced by allotting a subscriber's line to more than one node. In Fig. 7 (not shown) auxiliary cross-point matrices are employed for connecting any one of 2 (or 4) lines to any one of 2 (or 4) nodes. The arrangement may be extended to more than 2 co-ordinates, and it is found that for a given number of nodes an optimum result is obtained by suitable choice of the number of co-ordinates. The switches at the nodes may be of multi-position mechanical type, cross-bars or reed relays. The switches are conveniently controlled by a central processing unit CPU, Fig. 13, which obtains the addresses of the calling and called subscribers from a line scanner 102 and sends signals indicative of the shortest available path to a switch controller 105. If the CPU fails the memory of the network may be recaptured by the use of a network scanner 106.
